(make_cursor_line_fully_visible): Return 0 and set

fonts_changed_p if need larger matrices due to vscrolling.
(try_scrolling, try_cursor_movement, redisplay_window): Give up on
this round of redisplay if make_cursor_line_fully_visible fails.
(CURSOR_MOVEMENT_*, SCROLLING_*): New enumerators.
(try_cursor_movement, try_scrolling): Use them instead of
integers.
